托福阅读备考之长难句分析：深海底部环境

　　托福阅读长难句：深海底部环境

　　Totally without light and subjected to intense pressures hundreds of times greater than at the Earth’s surface，the deep—ocean bottom is a hostile environment to humans，in some ways as forbidding and remote as the void of outer space.

　　(定语后置in some ways…)

　　【译句】由于完全没有光，而且承受着比在地球表面大数百倍的极大压力，深海底部对人类而言是一个充满敌意的环境，在某些方面就像外层空间一样险恶和遥远。

　　分句1：Totally without light and subjected to intense pressures

　　分句2：hundreds of times greater than at the Earth’s surface

　　分句3：the deep—ocean bottom is a hostile environment to humans

　　分句4：in some ways as forbidding and remote as the void of outer space

　　分句2修饰分句1结尾的短语intense pressures，

　　分句1是分句3的状语

　　分句3是整个长句子的主句

　　分句4是分句3的后置定语，修饰分句3的a hostile environment to humans

　　主句前后分别有状语和定语的修饰成分，但是本句其实不是复合句。句子的核心意思是深海对于人类而言是一个充满敌意的环境。
